Research interests

I am particularly interested in the evolution of ecological interactions and how adaptive behaviour affects communities. Besides statistical and top-down approaches, I develop and analyze individual-based models to investigate the bottom-up mechanisms that define the structure and dynamics of ecological systems, focusing on the ecophysiology of woody plants, microbes and plasmids.

My research interest spans the following subjects:

Approaches Individual-based Ecology and Modelling Methods of Statistics and Computer Science
Area Plasmid Biology and Microbial Evolution Ecophysiology of Woody Plants

Current research deals with (i) the simulation of the feedback between xylem formation, hydraulic conductivity and water availability, (ii) the effect of deadwood management on reforestation dynamics and on (iii) the eco-evolutionary dynamics of root-grafted tree networks.

My PhD focused on the propagation of antibiotic resistances in aquatic environments. The prefered platform of antibiotic resistence genes are plasmids, which constitute important genetic elements for bacterial adaptation and diversity. I use mathematical models such as systems of ordinary differential equations, cellular automaton and individual based models to investigate mechanisms that influence plasmid transfer and persistence under various ecological conditions.

Check out the models PlasSim and PlasmidActionIBM in our model gallery

Through my GitHub account https://github.com/mzwanzig I provide access to the source code (+apps) of these models and, in addition, tools for data analysis with R, including a script-based guide for a systematic data exploration, steps for tree height model development and calibration as well as routines for fitting and analysing enzyme kinetics with the classical Michaelis Menten and a derivate approach that we named SINH, which is able to deal with the effect of substrate inhibition.
